Abstract
An electric discharge lamp apparatus incorporates: a metal lead support,which projects over the front surface of an insulating plug,made of synthetic resin, which supports the leading end of an arc tube,and which serves as a passage for electric power arranged to be supplied to the arc tube,; and an insulating sleeve,which is made of ceramics formed into a pipe shape and through which the lead support,is inserted, wherein a predetermined gap S,is provided between the insulating sleeve,and the lead support,. Thus, insertion of the lead support,into the insulating sleeve,can easily be performed, and a dimension error of the insulating sleeve,can be absorbed. Since a bent portions,is provided for a portion of the lead support,into which the insulating sleeve is inserted, the insulating sleeve,and the lead support,can hermetically integrated with each other. Thus, rattle of the insulating sleeve,with respect to the lead support,can be prevented.
